ORFS Interlock Hydraulic Hose Fitting: Series 24213-W

Why This ORFS Interlock Hydraulic Hose Fitting Passes the Compliance Gate

This ORFS interlock hydraulic hose fitting (series 24213-W) pairs an ORFS female flat face end with the O-ring face seal geometry of SAE J1453 / ISO 8434-3, crimped to SAE J516 / ISO 12151-1. The interlock design grips the wire reinforcement of spiral hose, so the joint holds under the high pressures those hoses carry. OEM buyers, hydraulic distributors and repair shops specify series 24213-W for high-pressure spiral hose circuits on construction and mobile equipment. The matrix below covers four part numbers from DN20 to DN40.

Core Advantages

• Interlock cage bites the spiral wire, giving a high-pressure joint built for tough duty; these ORFS fittings for spiral hose hold where braided crimps cannot.
• Flat face O-ring seal needs no tape or sealant and holds in high-pressure service.
• Female swivel nut allows the hose to be re-clocked after the joint is tightened.
• Cold-forged carbon steel, heat treated and trivalent zinc plated, 100% pressure tested.

Technical Specifications

What Is an ORFS Interlock Hydraulic Hose Fitting?

An ORFS interlock hydraulic hose fitting is a hose end whose crimp shell interlocks with the wire layers of a spiral (interlock) hose. Because the shell grips the reinforcement directly, this interlock O-ring face seal fitting is stronger than a standard braided-hose crimp and suits the higher working pressures of spiral hose.

The ORFS end still seals at the flat faces. The mating male end carries an O-ring in its face groove, and torquing the swivel nut compresses the ring between the two flat faces. This O-ring face seal is not interchangeable with JIC 37 degree (SAE J514), ORB (SAE J1926 / ISO 11926) or SAE 45 degree (SAE J513).

Dimensional Data

Full Dimension Table (Part Number Matrix)

Printed header (bilingual on the sheet): PART NO. | THREAD E | HOSE BORE DN | HOSE BORE DASH | DIMENSIONS A | C | S2. Code logic: 24213-<thread dash>-<hose dash>W, where “W” marks the interlock (spiral hose) version. The standard printed on the sheet is ISO 12151-1 – SAE J516.

Note: the printed sheet carries no footnote below the table. Series 24213-W is the interlock (spiral hose) counterpart of the braided-hose ORFS female families, and its counterpart code for braided hose is series 24211. Confirm the exact hose construction with our team before ordering.

Working Pressure and Operating Envelope

Working pressure is set jointly by the ORFS end connection and the hose grade, so always use the lower of the two ratings. Because this interlock O-ring face seal fitting is built for spiral hose, it is the right choice when the circuit pressure exceeds what braided hose can take. Every fitting is 100% pressure tested at the factory, and torque and crimp data sheets are supplied with each order. Typical service temperature is -40°C to +120°C, and any derating is governed by the hose and the O-ring.

Selection and Ordering

How to Read the Part Number Matrix

Each code follows 24213-<thread dash>-<hose dash>W. The first dash is the ORFS thread size, the second is the hose bore, and the trailing “W” marks the interlock spiral-hose version. Example: 24213-16-16W uses a 1.7/16″X12 thread with a -16 hose.

Cross Reference Service

Send us an OEM drawing or an old part number and we will map it to the closest ORFS interlock hydraulic hose fitting code. We translate thread size, hose dash and end style, then quote a like-for-like replacement. Because series 24213-W is intended as ORFS fittings for spiral hose, we confirm the hose construction and the interlock series before production. This makes a drop-in retrofit simple even when the incumbent number is not in our catalogue.

Emballage et logistique

Standard packing is 10 pcs per box with a batch box label on every carton. Origin is marked Made in China – HENGHUA, and an MTR is included with the shipment when required. Cartons are palletized for container loading and can be labelled to your own SKU scheme on request. Lead time is confirmed at quotation, with 24-hour response on price and availability.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square with a cut-off saw and clean any debris from the bore.
2. Mark the insertion depth on the hose cover using the data sheet.
3. Strip the cover to the required length so the interlock shell can engage the wire.
4. Crimp to the specified dimension, then verify the crimp OD with a vernier caliper.

Interlock fittings must be crimped with the correct shell and setting for the spiral hose in use. Never compensate a poor interlock crimp by over-torquing the swivel nut.

Connecting the ORFS End

Clean the flat face and check the O-ring before every assembly. Replace the O-ring if it is cut, flattened or hardened, then seat it fully in the groove. Thread the swivel nut on by hand until the faces touch, then torque to the value in the data sheet. The female swivel can be backed off to align the hose without breaking the seal, but never wrap the threads with tape or apply sealant.

Installation Warnings

• Do not mix fittings from different manufacturers on one joint.
• Do not join ORFS to JIC 37 degree, ORB or SAE 45 degree ends.
• Do not reuse or omit the O-ring, and do not install a cut or hardened ring.
• Do not fit an interlock series to braided hose, or a braided series to spiral hose.
• Do not crimp the ORFS interlock hydraulic hose fitting without the correct data sheet setting.
• Do use clean faces, a fresh O-ring and the specified torque every time.

OEM Customization and Quality Traceability

Customization Options

We offer laser marking and private labelling, plus custom threads and custom surface finishes. Special O-ring compounds, non-standard lengths and mixed kits can be produced to drawing. Tooling and sampling are quoted per project, with 24-hour response on enquiry.

Quality and Traceability System

Every batch is pressure tested and thread gauged, and each lot carries a batch number traceable through the full production flow. Material test reports are available on request, and third-party inspection by BV or SGS can be arranged. This lets OEM buyers and distributors close their own quality file with confidence.

FAQ

What is an ORFS interlock hydraulic hose fitting? It is an ORFS female hose end whose crimp shell interlocks with the wire layers of a spiral hose. The interlock grip gives a high-pressure joint suited to spiral hose service.

Why use an interlock fitting instead of a standard crimp? Spiral hose carries higher pressures and stiffer wire, so the shell must lock into the wire to hold. A standard braided-hose crimp is not intended for that duty, which is why ORFS fittings for spiral hose use an interlock shell.

How do I tell ORFS from JIC or ORB? Look at the end face: ORFS is flat with an O-ring groove. JIC 37 degree is a cone, and ORB is a straight thread with an O-ring on a boss face. ORFS threads also run about 1/16″ larger than the same JIC size.

Do I need sealant or thread tape? No. The O-ring in the face groove does the sealing, so tape or paste can actually cause a leak. Keep the face clean and torque to the data sheet.

Which hose sizes are covered? Series 24213-W is listed from -12 to -24 hose bore. For smaller braided-hose sizes, use the ORFS female braided family instead.

Can I use series 24213-W on braided hose? No. Series 24213-W is the spiral (interlock) version. For braided hose use the matching braided-hose ORFS female series, and confirm the construction with us.

Can you customise or private label the fitting? Yes. We offer laser marking, custom threads and custom finishes to your drawing, with 24-hour quotation.
